Sound projection device attachable to a user when not in use

Abstract

A megaphone comprises a rigid but bendable material with a tapered shape. When the material is folded, the produced megaphone has a small opening at one end and a larger opening at the other end. The megaphone has edges that form an opening along the side such that when pressure is applied to the edges the opening expands allowing the megaphone to be positioned on a person's arm or leg. Once positioned on the arm of leg the rigidity of the material causes the megaphone return to its original cone shape. The megaphone can enclose around a user's arm or leg for storage purposes during an event. Information can be displayed on the surface of the megaphone. The megaphone of the present invention can be folded and unfolded.

1. A device for projecting sound from a person into the atmosphere comprising:
 a sheet of generally rigid material having a surface with opposite ends; said sheet material having a front end and a back end, both end having different lengths, said back end having a length longer than the length of said front end; said sheet material having pair of side edges at each end of said front and back ends the edges, said generally rigid sheet material being configured such that when said side edges come together, said sheet of generally rigid material forms a tapered and general cone shape having an outer surface and an inner, said generally rigid material being capable of maintaining the general cone shape, being capable of expanding the cone shape at the edges to create an opening in the cone shape when pressure is applied to the edges in opposite directions to force the edges apart and capable reconfiguring to the original cone shape without external assistance aiding such reconfiguring when pressure on the edges is reduced; and 
 information being displayed on the outer surface of said rigid material when said rigid material is formed into a general cone shape. 
 
     
     
       2. The device as described in  claim 1  further comprising on the edges magnetic strips such that magnetic forces from the strips attract to each other and further secure the general cone shape of the material. 
     
     
       3. The device as described in  claim 1  further comprising a transparent sheet material attached to outer surface of the device such that a pocket is formed between the transparent sheet material and the outer surface of the sheet material, the pocket capable of containing information for display on the surface of said sheet material. 
     
     
       4. The device as described in  claim 1  further comprising a lining attached to the inner surface of said generally cone shape material, said lining capable of providing insulation against low temperatures. 
     
     
       5. The device as described in  claim 1  wherein said front and back ends can be used to channel light through the device. 
     
     
       6. The device as described in  claim 1  wherein said front end has a length such that an inner circumference of the front end will securely fit around a user's wrist area. 
     
     
       7. The device as described in  claim 6  wherein said front end has a length in the range of 9 inches to 13 inches. 
     
     
       8. The device as described in  claim 1  wherein said front end has a length such that an inner circumference of the front end will securely fit around a user's ankle area. 
     
     
       9. The device as described in  claim 8  wherein said front end has a length in the range of 10 inches to 14 inches. 
     
     
       10. A device for projecting sound from a person into the atmosphere comprising:
 a sheet of generally rigid material having surface with opposite ends; said sheet material having a front end and a back end, both end having different lengths, said front end having a length in the range of 9 inches to 14 inches said back end having a length longer than the length of said front end, said back end having a length in the range of 13 inches to 20 inches; said sheet material having pair of side edges at each end of said front and back ends each said edge forming a tapered shape when the edges come together, said generally rigid sheet material being configured such that when said side edges come together, said sheet of generally rigid material forming a general cone shape having an outer surface and an inner, said generally rigid material being capable of maintaining the general cone shape, being capable of expanding the cone shape at the edges to create an opening in the cone shape when pressure is applied to the edges in opposite directions to force the edges apart and capable reconfiguring to the general cone shape without external assistance aiding such reconfiguring when pressure on the edges is reduced; and 
 information being displayed on the outer surface of said rigid material when said rigid material is formed into a general cone shape. 
 
     
     
       11. A device for projecting sound from a person into the atmosphere comprising:
 A sheet of flexible, bendable material, capable of reconfiguration without external assistance aiding such reconfiguration, having a surface with opposite sides; said sheet material having a front edge and a back edge, each edge having opposite ends, both edges having different lengths, said back edge having a length longer than the length of the front edge; said sheet material having a pair of side edges at each end of said front and back edges; 
 An adhesive material attached to each side edge of said sheet material; and 
 A transparent sheet material attached to said flexible sheet material such that a pocket is formed between the transparent sheet material and said flexible sheet material, the pocket capable of containing information for display on the surface of said sheet material; and 
 Information displayed on the surface of said sheet material. 
 
     
     
       12. The device as described in  claim 11  further comprising transparent sheets on both sides of the flexible sheet material. 
     
     
       13. The device as described in  claim 11  wherein said adhesive material comprises a magnetic material. 
     
     
       14. The device as described in  claim 11  wherein said adhesive material has a width that can vary enabling a user to adjust the device.
